vl M PROVEM ENT IN LAM PS.

Specification forming part of Iietters Iatent No. 103,011, dated Mayhl7, 1870.-

To "alt whom it may concern:

Beit known that I, ABNER BURBANK, of

- the city of Rochester., in Vthe lcounty of Monroe and State of New York, have invented new and useful Improvement-s in Lamps, of which the following is a specification:

Nature of Invention.

General Description.

Figure l is an elevation showing a portion of a building and my improved arrangement connected therewith; Fig. 2, a section of one form of lamp illustrating my improvement.

A A represent a system of pipes distributed through buildingB in the ordinary manner of gas-pipes. At the bottom these pipes connect with some` arrangement for blowing in air, which may be of any desired kind.

In the drawings is shown a gasometer, C, of common construction, which is fed with air by means of a supply-pipe, D, leading to forcepump E, operated by gearing G, driven by Weight or spring.

H represents the lamp. It consists of a reservoir, J, having a struck-up bottom, K, 4which forms a cavity, L, in said bottom.

A tube, M, extendsv from the top plate ofthe lamp to the bottom plate thereof, and forms a central opening, N, through which the current of air is to be passed. In said openings N is placed a tube, O," which forms a chamber for the wick. It will be noticed that said tube is sufficiently small to allow a considerable space between it and the tube M. l

l)` is the cone-burner, which has the usual slot for the wick and iiame, but has not the air-openin gs which exist in the ordinary burners. This burner is supported on the collar which rests on the top of the reservoir, or may be screwed or otherwise secured thereto; and within the collar and cone is a wick-tube, whose lower portion is made to rest snugly on the topof wick-chamber O, or may be screwed or., otherwise connected thereto.

about the point of combustion.

It will now be perceived that air passing up through opening N around the wick-chamber continues through the collar and cone inside thereof, and supplies the ilame therewith at or The communication between the reservoir J and wickchamber-may be made by 4means of a tube, Q, suitably arranged.

The lamp thus constructed is to be supported on a bracket, It, which is secured to the airpipe A, and communicates therewith. by an opening, a, in its bottom, and this bottom isso struck up at R' as to form a cavity, S, which, with the cavity L, constitutes an air-chamber. The lamp must t snugly in the bracket It, so that the air cannot escape between them.

When the air comes from the pipe A it enters and fills the air-chamber Il S, and then passes with an equalized pressure to the burner. The lamp may be applied to side,l

drop, and other lights by properly arranging the portion of the pipe A which supports the lamp.4

The other part of the pipe need not necessarily be fixtures of the house similar to gaspipes; but portable pipes of ilexiblematerial may be employed for the samey purpose.

The bracket R may be soldered to the lamp and the two be screwed to the air-pipes, or the latter may have a conical socket to receive the bottom of the bracket portion.v In this case the upper sides of the bracket are unnecessary.

Among the advantages of this method are,

that oil may be burned with thevsame facility dinary lamp-light or to gas; consequently all smoke and offensive smell is obviated.

In addition to the above, the current of cold air coming in contact with the lamp keeps the same always cool, thereby preventing the formation of gas, and obviatin g the explosions so common in ordinary lamps.

This improvement is not only easily applied to buildings with pipes laid expressly for the purpose, but also to ordinary gas-pipes and xtures already in place where gas is discontinued. It is only necessary to secure the lamps upon the fixtures and force a blast of air through the pipes in contact with the llame.

I am aware ofthe ordinary portable gas apparatus, in which air impregnated with naphtha orbenzine is forced through pipes to be burned;

Claims.

What I claim, and desire to secure by Letters Patent, is-

1. The lamp H, constructed substantially as described, the bracket R, and air-pipe A, combined and operating as set forth.

2. The air-chamber L S, formed by the bottom K of the reservoir and the bottom It of bracket, substantially as and for the purpose described.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

ABNER BURBANK.
